▼ This thesis looked at regional disaster resilience with a specific focus on economic loss of energy infrastructure disruption from a seismic hazard impact. This thesis discusses typical damage sustained by regions from energy disruption and representative earthquake damage specific to energy infrastructure. Due to its seismic risk, geographically concentrated energy infrastructure, and state-level agencies interested in energy infrastructure resilience, Oregon was used as a selected study to model energy infrastructure disruption. The economic interdependencies of Oregon's energy infrastructure, broader critical infrastructure, and Oregon's commercial economy are determined through an Input-Output (IO) economic impact model. IMPLAN provided the economic data and model software for all of Oregon for 2008. A sector aggregation scheme was developed to represent Oregon's economy as 19 sectors with emphasis on the energy infrastructure sectors of petroleum, electricity, and natural gas. The IO developed for Oregon in 2008 can be seen in Appendix A. A representation of output of the energy infrastructure sectors was then manipulated with impact scenarios in order to represent seismic hazard damage in the seismic disaster context. 16 impact scenarios were developed with varying degrees of final demand change ranging from one or all three energy infrastructure sectors being disrupted. Direct, indirect, induced, and total changes in all sectors for output, employment, labor income, and value added for every impact scenario were then analyzed. For the largest impact scenario, a total of 3% total output change for all of Oregon as well as a minimum of 2.42 jobs would be expected to be lost for every direct job lost in the energy sectors. The sectors of transport by pipeline, mining, transport by rail, and utilities will be more impacted than other sectors in Oregon's economy due to energy infrastructure disruption. Additionally, this thesis infers electricity is more important than petroleum and natural gas to everyday life in Oregon. Petroleum is important to the production of itself, the regional economy, and the production of all other energy infrastructure sectors. Therefore, regions should strive for petroleum to be the energy sector most resistant to damage and electricity to be the energy sector able to quickly regain output to enhance regional disaster resilience with respect to energy infrastructure. IO is a good first building block for more involved economic impact models but a more representative model would allow for substitution. Future work should also develop a way to incorporate IO and impact results into a recovery model for both components of resilience (loss and recovery) to be modeled.

▼ Flow directions and catchment algorithms have historically utilized raster-based data models. A significant body of literature focuses on raster-based interpolation errors, and the subsequent surface reconditioning to compensate for those errors, that together degrade the accuracy of the derived flow directions and catchments. This research seeks to improve upon the raster-based approach by developing and evaluating a vector-based approach to generating flow directions and delineating catchments that preserves the accuracy of the input point data through the use of irregular tessellated surface models. Specifically, the Python computer programming language was used in conjunction with a geographic information system (GIS) to develop ITSMHydro, a custom toolset that creates a Delaunay triangulated irregular network (TIN) from LiDAR bare-earth sample point data, and subsequently generates flow directions, delineates basins, and processes spurious sink catchments. Surface model accuracy, and area, shape, and overlap of the resulting catchments were compared with catchments delineated using industry-standard raster-based digital terrain models. The vector-based approach implemented through ITSMHydro was limited to file sizes less than approximately 120,000 LiDAR strikes that processed in approximately 30 hours, whereas the industry-standard raster-based approach transformed 111,000,000 LiDAR strikes across the study area into a 3-feet pixel surface model and generated catchment boundaries in approximately 36 hours. A root mean square analysis of surface models indicates that surface model quality is more heavily degraded when LiDAR sample points are interpolated to raster grids as opposed to surface models relying on Delaunay TIN interpolation, suggesting that the vector-based approach maintains the quality and precision of the LiDAR input data. For the four test areas in which the two approaches were compared, ITSMHydro generated catchments that were generally smaller (percent difference in areas ranged from -83.97% to 9.39%) and with more complex boundaries (i.e. lower isoperimetric quotient in 3 out of 4 test areas) than the associated raster-based catchments. Coefficient of areal correspondence (CAC), a measure of overlap between catchments generated by the two methods where a value of 1 indicates perfect overlap, ranged from 0.28 to 0.80 in the four test areas. Given the lower relative accuracy of raster-based surface models evident in the study area, these differences suggest use of the raster-based approach may compromise accuracy in area, shape, and location of the resulting catchments. A vector-based approach that preserves the accuracy of the input data is preferred, especially in areas of low topographic relief. The file size constraints limit application of the approach developed herein, however, at least until technological advances and/or code revisions improve computer processing speed and file size capacity.
